AMD "has a potent combination of both CPU and GPU technologies," writes Slashdot reader MojoKid, that "can play well in the laptop market especially, where a tight coupling of the two processing engines can mean both performance and cost efficiencies." One of the first all-AMD laptops to hit the market powered by the company's new Ryzen 4000 mobile processors is the Dell G5 15 SE, it's a 5.5 pound, 14.4-inch machine [with a 15.6-inch display] that sports an understated design for a gaming notebook but with an interesting glittery finish that resists fingerprints well. With a retail price of $1199 (starting at $879), the model tested at HotHardware is powered by an AMD Ryzen 4800H 8-core processor that boosts to 4.2GHz and an AMD Radeon RX 5600M mobile GPU with 6GB of GDDR6 memory...

In the benchmarks, AMD's SmartShift technology load-balances CPU and GPU power supply for optimal performance and very respectable numbers that are competitive with any similar Intel/NVIDIA powered machine. The Dell G5 15 SE put up north of 60 FPS frame rates at maximum image quality in current-gen game titles, but with a significantly better price point, relatively speaking.
The GPU also has 2,304 stream processors across 36 compute units, and "Overall, we think Dell hit it out of the park with the new G5 15 SE," the review concludes.

"This all-AMD budget blockbuster has all of the gaming essentials: a fast processor, a powerful GPU, and a 144 Hz display."

An anonymous reader quotes a report from ZDNet: Some 66 million years ago, an asteroid hit the Earth on the eastern coast of modern Mexico, resulting in up to three quarters of plant and animal species living on the planet going extinct -- including the dinosaurs. Now, a team of researchers equipped with a supercomputer have managed to simulate the entire event, shedding light on the reasons that the impact led to a mass extinction of life. The simulations were carried out by scientists at Imperial College in London, using high performance computing (HPC) facilities provided by Hewlett Packard Enterprise. The research focused on establishing as precise an impact angle and trajectory as possible, which in turn can help determine precisely how the asteroid's hit affected the surrounding environment.

Various impact angles and speeds were considered, and 3D simulations for each were fed into the supercomputer. These simulations were then compared with the geophysical features that have been observed in the 110-mile wide Chicxulub crater, located in Mexico's Yucatan Peninsula, where the impact happened. The simulations that turned out to be the most consistent with the structure of the Chicxulub crater showed an impact angle of about 60 degrees. Such a strike had the strength of about ten billion Hiroshima bombs, and this particular angle meant that rocks and sediments were ejected almost symmetrically. This, in turn, caused a greater amount of climate-changing gases to be released, including billions of tonnes of sulphur that blocked the sun. The rest is history: firestorms, hurricanes, tsunamis and earthquakes rocked the planet, and most species disappeared from the surface of the Earth. The 60-degree angle constituted "the worse-case scenario for the lethality of the impact" because it maximized the ejection of rock and therefore, the production of gases, the scientists wrote.

"The researchers carried out almost 300 3D simulations before they were able to reach their conclusions, which was processed by the HPE Apollo 6000 Gen10 supercomputer located at the University of Leicester," adds ZDNet. "The 14,000-cores system, powered by Intel's Skylake chips, is supported by a 6TB server to accommodate large, in-memory calculations."

Linus Torvalds released Linux 5.7 rc7 today, saying it "looks very normal... none of the fixes look like there's anything particularly scary going on."

But then he added something else: [T]he biggest excitement this week for me was just that I upgraded my main machine, and for the first time in about 15 years, my desktop isn't Intel-based. No, I didn't switch to ARM yet, but I'm now rocking an AMD Threadripper 3970x. My 'allmodconfig' test builds are now three times faster than they used to be, which doesn't matter so much right now during the calming down period, but I will most definitely notice the upgrade during the next merge window.
The Register writes: Torvalds didn't divulge any further details about his new rig, but the 3970x is quite the beast, boasting 32 cores and 64 threads at 3.7GHz with the ability to burst up to 4.5GHz, all built on TSMC's 7nm FinFET process... Torvalds has probably acquired a whole new PC, as the Threadripper range requires a sTRX4 socket and those debuted on motherboards from late 2019.

Whatever he's running, it has more cores than Intel currently offers in a CPU designed for PCs. Even Chipzilla's high-end CoreX range tops out at 18 cores. AMD will be over the moon that such a high profile IT pro has adopted their kit and pointed to its performance.
Or, as long-time Slashdot reader williamyf puts it, "Good endorsement for AMD, a PR blow for Intel."

MojoKid writes: A couple of weeks back, Intel announced its 10th Gen Core desktop processors but today the embargo has been lifted on performance data. Intel's new 10th Gen Core series desktop chips are still based on the same architecture and leverage the same 14nm++ manufacturing process as their 9th Gen predecessors, but the company made numerous changes with Comet Lake-S in an attempt to deliver even more performance, efficiency, and value. A review of the new chips at HotHardware details features and performance of a couple of the stand-outs in Intel's initial 10th Gen Core series line-up -- the flagship Core i9-10900K and mid-range Core i5-10600K.

The Core i9-10900K features a monolithic, 10-core (20-thread) die that boosts to 5.3GHz, while the Core i5-10600K offers 6 cores / 12-threads at a 4.8GHz boost clock. Although the architecture is the same as the previous-gen, Intel has tuned its 10th Gen's frequency and voltage curves to boost performance and optimize power. The Core i9-10900K ends up being a significant upgrade over its predecessor, but more-so for multi-threaded tasks. The Core i5-10600K, however, is a decent upgrade over the previous-gen Core i5-9600K, in terms of both single- and multi-threaded performance. Both CPUs deliver competitive performance versus similarly-priced Ryzen 3000 series chips from AMD, though Intel retains an edge in gaming, while AMD delivers better overall multithreaded performance.

The Senate has voted to reauthorize the USA Freedom Act without adding an amendment that would have restricted warrantless collection of internet search and web browsing data. It did however adopt an amendment to expand oversight. The Verge reports: The USA Freedom Reauthorization Act restores government powers that expired in March with Section 215 of the Patriot Act. The [Act] lets law enforcement collect "tangible things" related to national security investigations without a warrant, requiring only approval from a secret court that has reportedly rubber-stamped many requests. It passed the House of Representatives earlier this year, but it stalled in the Senate during the start of the coronavirus pandemic. Today, senators approved it with 80 votes for and 16 votes against, according to The Hill. The House of Representatives will need to approve the amended version of the bill before sending it to the president's desk.

The USA Freedom Act was designed to reform the Patriot Act and limit large-scale phone record collection, following leaks from NSA contractor Edward Snowden in 2013. But surveillance critics wanted to extend its limits in the reauthorized version. Sens. Mike Lee (R-UT) and Patrick Leahy (D-VT) successfully passed an amendment that would expand the role of independent advisers to the Foreign Intelligence Surveillance Act (FISA) court. Conversely, Sens. Ron Wyden (D-OR) and Steve Daines (R-MT) failed by one vote to pass a rule prohibiting warrantless surveillance of internet search and browsing records. Wyden ultimately voted against the reauthorization.

Alienware has announced the second generation of its flagship Area-51m gaming laptop, the Area-51m R2. It's largely similar on the outside to the original Area-51m, but the specs are almost completely overhauled on the inside, with 10th Gen Intel processors, new Nvidia GPUs, faster RAM, and better display options. From a report: All of those upgrades will be limited to the new R2 model, though. Despite Alienware's goals for future-proofed upgradable parts, the Area-51m has failed to live up to its potential. One of the biggest draws of the Area-51m was the option for user-replaceable parts. Most modern laptops have nearly all of their internal components sealed in place in an effort to cut down on size. But the Area-51m took a different approach. It was big, easy to disassemble, and made it simple to replace nearly every internal component, from RAM to the CPU to the GPU to even the thermal cooling components. The idea was to make something more portable than any other desktop but more customizable than any laptop. Alienware's parent company, Dell, even built its own system for replaceable GPUs in laptops, called DGFF (Dell Graphics Form Factor) to make it easier to upgrade in the future.

The Trump administration and semiconductor companies are looking to jump-start development of new chip factories in the U.S. as concern grows about reliance on Asia as a source of critical technology. From a report: A new crop of cutting-edge chip factories in the U.S. would reshape the industry and mark a U-turn after decades of expansion into Asia by many American companies eager to reap investment incentives and take part in a robust regional supply chain. The coronavirus pandemic has underscored longstanding concern by U.S. officials and executives about protecting global supply chains from disruption. Administration officials say they are particularly concerned about reliance on Taiwan, the self-governing island China claims as its own, and the home of Taiwan Semiconductor Manufacturing Co., the world's largest contract chip manufacturer and one of only three companies capable of making the fastest, most-cutting-edge chips.

Trump administration officials are in talks with Intel Corp., the largest American chip maker, and with TSMC, to build factories in the U.S., according to correspondence viewed by The Wall Street Journal and people familiar with the discussions. "We're very serious about this," said Greg Slater, Intel's vice president of policy and technical affairs. Mr. Slater said Intel's plan would be to operate a plant that could provide advanced chips securely for both the government and other customers.

A new set of flaws discovered in the Intel Thunderbolt port has put millions of machines at risk of local hacking. This new research by Eindhoven University's Bjorn Ruytenberg suggests that if a hacker gains access to a machine for just five minutes, they could bypass login methods to gain full data access. From a report: Thunderbolt ports are present in machines with Windows, Linux, and macOS. So, that covers a lot of computers. Ruytenberg said all Thunderbolt versions and systems shipped between 2011 to 2020 are affected and no software patch can fix these vulnerabilities. So, Intel would need to redesign silicon in order to fix these flaws. There's not much you can do here. However, with open-source software called Thunderspy, developed by Ruytenberg and their team, you can check if you're affected by the Thunderbolt bug.

Microsoft and Intel have collaborated on a new research project that explores a new approach to detecting and classifying malware. From a report: Called STAMINA (STAtic Malware-as-Image Network Analysis), the project relies on a new technique that converts malware samples into grayscale images and then scans the image for textural and structural patterns specific to malware samples. The Intel-Microsoft research team said the entire process followed a few simple steps. The first consisted of taking an input file and converting its binary form into a stream of raw pixel data. Researchers then took this one-dimensional (1D) pixel stream and converted it into a 2D photo so that normal image analysis algorithms can analyze it.

Reuters reports that the Trump administration "is in talks with semiconductor companies about building chip factories in the United States, representatives from two chipmakers said on Sunday." Intel Corp is in discussions with the United States Department of Defense over improving domestic sources for microelectronics and related technology, Intel spokesman William Moss said in an emailed statement. "Intel is well positioned to work with the U.S. government to operate a U.S.-owned commercial foundry and supply a broad range of secure microelectronics", the statement added.

Taiwan Semiconductor Manufacturing Co, on the other hand, has been in talks with the U.S. Department of Commerce about building a U.S. factory but said it has not made a final decision yet. "We are actively evaluating all the suitable locations, including in the U.S., but there is no concrete plan yet", TSMC spokeswoman Nina Kao said in a statement...

The Wall Street Journal had also reported that U.S. officials are looking at helping South Korea's Samsung Electronics, which has a chip factory in Austin, Texas, to expand its contract-manufacturing operations in the United States.

Intel compromised worker safety at some of its factories to maintain chip production in the midst of the Covid-19 pandemic, according to complaints filed with government agencies and employees at one of the sites. From a report: At a plant in Chandler, Arizona, the world's largest semiconductor maker did not isolate staff that worked closely with teammates who had tested positive and did not institute tests, people who work there said. Factory managers also dismissed concerns that social-distancing guidelines were not being followed properly, according to the people, who asked not to be identified because they fear sanction by their employer. Many of these virus-related concerns were also raised in filings to state agencies that regulate workplace safety. The company said it responded with new policies to improve employee safety and kept factory output high because its products are essential.

MojoKid writes: AMD unveiled two new Ryzen 3 processors recently, designed to drive its Zen 2 CPU microarchitecture into more affordable price points. The new Ryzen 3 3100 and Ryzen 3 3300X are entry-level 3rd gen Ryzen CPUs that will run in any socket AM4 motherboard, with price points of only $99 (Ryzen 3 3100) and $120 (Ryzen 3 3300X). They are both quad-core/eight-thread chips, with similar cache configurations (2MB L2 + 16MB L3), and they both include basic Wraith Stealth coolers in their retail boxes. Internally, however, these two processors are somewhat different. The Ryzen 3 3100 is setup in a 2+2 configuration with two cores active per CCX (CPU Core Complex). The Ryzen 3 3300X, however, has a 4+0 configuration, with all of its active cores residing on a single CCX. These differences should result in better overall performance for the Ryzen 3 3300X, over and above just having a higher peek clock speed of 4.3GHz, versus 3.90Ghz for the Ryzen 3 3100. In the benchmarks, these new AMD quad-core chips offer similar or better performance versus competitive Intel Core i5 chips, but at significantly lower price points.

Ammalgam shares a report from Redmond Pie: Microsoft has officially announced the Surface Book 3. Not much has changed for the device in terms of external design, but internal circuitry is where it's at. This newest addition to the Surface family was formally unveiled alongside the Surface Go 2 today. And the detachable PC finally got the long overdue refresh. Microsoft decided to go with the latest Intel 10th generation CPUs, codenamed Ice Lake. There was talk that the company might opt for the Comet Lake processors. Both are 10th generation chips, but Ice Lake is made on a 10nm process, while Comet Lake is 14nm. [...] As for the CPU options, we have the Core i5-1035G7 and Core i7-1065G7 available. The Core i5 models don't offer dedicated graphics, while the 15-inch variant of the Surface Book 3 only comes in the Core i7 flavor. GPU got a real look, too. The 13.5-inch Surface Book 3 gets you the 4GB Max-Q variant of the NVIDIA GeForce GTX 1650, while the 15-inch one comes with a GTX 1660 Ti Max-Q with 6GB.

On the display side, we have a 3000 x 2000 screen on the 13.5-inch model, while the 15-inch one offers a resolution of 3240 x 2160. Microsoft also claims that the Surface Book 3 has the best battery life of any device it has made up until now. It's rated at 17.5 hours on the 15-inch model and 15.5 hours on the 13.5-inch variant. Some neat improvements when it comes to port selection, with both the USB Type-A and Type-C ports now being USB 3.1 Gen 2, meaning you get 10Gbps instead of 5Gbps. There is also a Surface Connect port on both the base and the tablet, to go with the 3.5mm audio jack in the tablet. All these enhancements mean that the starting price of the Surface Book 3 is a bit higher at $1,599. It will be available on May 21.

Chipmaker Intel has bought Israeli public transit app maker Moovit for about $900 million to help it develop self-driving "robotaxis" that could take to the streets in early 2022, the company said. From a report: Moovit will remain independent while its technology and the data it collects from more than 800 million users in 102 countries will be integrated into Intel's Israel-based autonomous car unit Mobileye. The deal talks started with Moovit seeking to do a capital raise before the novel coronavirus outbreak globally, according to a source familiar with the negotiations. Moovit had enough cash to sustain itself for about a year, and when the economic impact of the pandemic became evident, it decided to explore an outright sale to Intel, the source added. The deal was negotiated in 40 days through virtual meetings, according to the source.

Sooner than expected, Apple has announced a new 13-inch MacBook Pro with a Magic Keyboard. It features optional Intel 10th Gen processors and starts at $1,299. In one sense, it is a minor spec-bump upgrade for the existing lineup of 13-inch MacBook Pros. But it also represents the end of an era: Apple no longer sells any new laptops with the much-maligned butterfly keyboard mechanism. From a report: Apple has moved relatively quickly to cycle out the butterfly keyboard from its lineup. The 16-inch MacBook Pro was announced in November 2019, followed by a refreshed MacBook Air with Magic Keyboard this past March. In the span of six months, Apple has completely swapped out its entire laptop lineup with models that use better scissor-switch keyboards. Compare that to the five years it spent trying to make the butterfly keyboard mechanism work since the 2015 MacBook (now discontinued). As with the last MacBook Pro, Apple is sticking with Thunderbolt 3 / USB-C connectors, two or four of them in total (plus a headphone jack). The Touch Bar also remains for better or worse, alongside a Touch ID fingerprint sensor and -- praise be -- a real, physical Esc key. The RAM can be upgraded to 32GB and the storage can be specced all the way up to 4TB. Apple says that 10th Gen Intel processors have a turbo boost up to 4.1Ghz and that the new Intel Iris graphics support the Pro Display XDR at full 6K resolution.

Charlotte Web writes: The U.S.-based research non-profit Ecohealth Alliance has spent 20 years investigating the origins of infectious diseases like Covid-19 in over 25 countries, "to do scientific research critical to preventing pandemics."

America just cut it's funding.

Trump's reason? "Unfounded rumors" and "conspiracy theories...without evidence," according to reports in Politico and Business Insider. The group had received a total of $3.7 million through 2019 (starting in 2014), publishing over 20 scientific papers since 2015 on how coronaviruses spread through bats, including at least one paper involving a lab in China. But during a White House press briefing, a conservative web site incorrectly stated the whole $3.7 million had gone to that single lab, while even more erroneously implying that that lab was somehow the source of the coronavirus. They'd then asked "Why would the U.S. give a grant like that to China?" and President Trump vowed he would revoke the (U.S.-based) nonprofit research group's grant, which he did 10 days later.
Slashdot referenced that research nonprofit just this Sunday, citing a recent interview with the group's president who'd said they'd found nearly 3% of the population in China's rural farming regions near wild animals already had antibodies to coronaviruses similar to SARS. "We're finding 1 to 7 million people exposed to these viruses every year in Southeast Asia; that's the pathway. It's just so obvious to all of us working in the field."

Yet Thursday Politico reported the Trump administration "has been pressuring analysts, particularly at the CIA, to search for evidence that the virus came from a lab and that the World Health Organization helped China cover it up," citing a person briefed on those discussions. People briefed on the intelligence also told them there is currently no evidence to support that theory.

Michael Morell, the former acting director and deputy director of America's CIA, also pointed out Thursday that the lab in question was in fact partially funded by the United States. "So if it did escape, we're all in this together."

UnknowingFool writes: Intel released more information about their next generation CPUs, codenamed Comet Lake. Overall, CPUs will get more cores and threads and slight speed boosts. Price wise, Intel is cutting prices to be more competitive with AMD's Rzyen processors. Some of the downsides include requiring new socket (thus new MBs), LGA 1200 and lack of PCIE 4.0 compatibility. No specific benchmarks were released, however Intel claims to have the fastest gaming CPUs. "[T]he top Comet Lake chip is the same price as the top Coffee Lake at $488, and the cheapest Core i3 is $122," reports PC Gamer. They expect the release date to be sometime in May, though no official date has been confirmed.

An anonymous reader quote Hot Hardware: If you're looking for the best gaming CPU or the best CPU for desktop applications, there are only two choices to pick from: AMD and Intel. That fact has spawned an almost religious following for both camps, and the resulting flamewars, that make it tricky to get unbiased advice about the best choice for your next processor.

But in many cases, the answer is actually very clear. In fact, for most users, it's a blowout win in AMD's favor. That's an amazing reversal of fortunes for the chipmaker after it teetered on the edge of bankruptcy a mere three years ago, making its turnaround all the more impressive as it continues to upset the entrenched Intel that enjoyed a decade of dominance... Pricing is the most important consideration for almost everyone, and AMD is hard to beat in the value department. The company offers a plethora of advantages, like bundled coolers and full overclockability on all models, not to mention complimentary software that includes the innovative Precision Boost Overdrive auto-overclocking feature.

You also benefit from the broad compatibility of Socket AM4 motherboards that support both forward and backward compatibility, ensuring that not only do you get the most bang for your processor buck, but also your motherboard investment. AMD also allows overclocking on all but its A-Series motherboards (see our article on how to overclock AMD Ryzen), which is another boon for users. And, in this battle of AMD vs Intel CPUs, we haven't even discussed the actual silicon yet. AMD's modern processors tend to offer either more cores or threads and faster PCIe 4.0 connectivity at every single price point.
"We're not covering laptop or server chips," the article notes, adding "There's a clear winner overall, but which brand of CPU you should buy depends most on what kind of features, price and performance are important to you."

Still, it's noteworthy that AMD beats Intel in 7 out of 10 comparisons. The three in which Intel won were gaming performance ("only because we measure strictly by the absolute top performance possible"), drivers and software ("the company has an army of software developers [and] a decade of dominance also finds most software developers optimizing almost exclusively for Intel architectures"), and overclocking, where Intel "has far more headroom and much higher attainable frequencies.

"Just be prepared to pay for the privilege."

Intel CEO Bob Swan cited a quote from former CEO Andy Grove as particularly apt during the pandemic. In a call with analysts, Swan noted that Grove once said, "Bad companies are destroyed by crises; good companies survive them; great companies are improved by them." From a report: Swan made the remarks after reporting what he said were "outstanding" results for both earnings and revenues in the "incredibly challenging" first quarter. But investors were spooked and drove the stock down 5% in after-hours trading, in part because Intel decided not to offer full financial guidance for all of 2020, due to uncertainties in the market. Intel also said its gross profit margins, or the money it makes on the sale of its products, would likely be lower in the second quarter. That is in part because the company is recording higher expenses as it prequalifies the manufacturing of its second generation of 10-nanometer products -- which is considered a normal expense in a process technology transition.
